SCAFFOLD BRACKET.

Application filed February 13, 1929. Serial No. 389,636.

This invention relates to brackets especially adapted for supporting ascaffold during the construction of a building, an object being toprovide a bracket which may beused as a scaffold support when applyingsheathing, sheathing paper and shingles, or brick and other veneer tothe outside of a building.

Another object of the invention is the provision of a bracket of theabove character which may be quickly adjusted for use, and in which theload will assist in holding the bracket in position.

With the above and other objects in view, the invention further includesthe following novel features and details of construction, to behereinafter more fully described, illustrated in the accompanyingdrawings and pointed out in the appended claims.

In the drawings: v

Figure 1 is an elevation of a bracket con structed in accordance withthe invent-ion and shown in position for use.

Figure 2 is a front view.

Figure 3 is a top view showing the studding of a building in section.

Figure 4 is a plan view of the clamp.

Figure 5 is an edge view of the same.

Figure 6 is a front elevation of the foot.

Figure 7 is a section on the line 77 of Figure 6.

Figure 8 is a fragmentary perspective view showing the outer end of oneof the bars of the bracket.

Figure 9 is a detail perspective view of one of the stud engagingmembers.

Referring to the drawings in detail wherein like characters of referencedenote corresponding parts, the reference character 10 indicates a pairof stud engaging members which may be formed as shown of a single lengthof material shaped to provide spaced apertured cars 11 for the receptionof pivot pins 12. These pins serve to pivotally connect the inner endsof substantially horizontally disposed arms 13 to the stud engagingmembers 10 and the latter are held in posi tion upon the studs 14 bymeans of pins 15, or through the medium of pins 16 which pass throughthe sides of the stud engaging members and enter openings provided inthe studs. The pins are secured to the stud engaging members by chains17 so that they will not become lost and the pins 16 may be likewisesecured if desired.

The arms 13 are adapted to extend outward and are shaped so that theirouter ends are relatively close and are pivotally connected to a clampwhich is indicated generally by the reference character 18 in F igure 4of the drawings. This clamp comprises a wedge 19 having an opening 20therein, while extending through this wedge are spaced cars 21 whichcarry a pivot pin 22. The outer ends of the arms 13 are pivotallysecured to the wedge by means of this pin..

Movable freely within the opening 20 provided in the wedge 19 is asubstantially T- shaped link 23 which extends beyond the inclined edgesof the wedge and is provided with openings 24. The link 23 is alsoprovided with an elongated slot 25 through which the pivot pin 22passes, sothat the link which is received between the outer ends of thearms 13 has a sliding pivotal connection with these arms.

The openings 24 of the link 23 receive the outer ends of inclined bars26. These bars are provided with notches 27 which are engaged by thelink and their lower inner ends are mounted upon a pivot pin 29 which iscarried by spaced ears 30. These ears form a part of a foot 31 which isadapted to bear against the sheathing or wall 32 which is carried by thestuds 14. This foot is pivotally secured to the lower ends of hangerbars 33 whose upper ends are secured to the members 10 as shown at 34.

The foot 31 is provided with spaced lugs 35 having notches to receivethe pivot pin 29 and these lugs serve to space the lower ends of thebars 26 apart.

In the use of the invention for applying sheathing to studding, thesheathing is applied in the ordinary manner to a desired height. Thesheathing is then notched as shown at 36 in Figure 3 of the drawings,the notch being of a sufiicient depth to receive the stud engagingmembers 10. This permits of the stud engaging members being positionedso as not to interfere with the continuation of the sheathing. The bars26 are then inserted within the openings 24 of the link 23, the saidbars having a sliding fit within these openings. The link is engagedwithin the notches 27 and the weight of the scaffold (indicated by thedotted lines S in Figure 1 of the drawings) will act to force the wedge19 between the bars so that the link will be firmly seated within thenotches 27. The wedge may move independently of the link due to thesliding engagement between the link and wedge'and the elongated slot 25in said link. It will be apparent that increased load upon the scaffoldwill only serve to force the wedge further outward between the bars 26 vand thus increase the clamping or gripping action.

\Vhile the bracket is shown and described in connection with a buildingunder construction, it is obvious that it may be used by inserting thestud engaging members 10 through a window or other opening in a buildingand engaging these members with studding temporarily positioned withinthe window. The foot which carries the inclined bars 26 will then engagethe outer face of the building.

The invention is susceptible of various changes in its form, proportionsand minor details otconstruetion and the right is here in reserved tomake such changes as properly fall within the scope of the appendedclaims.

Having described the invention what is claimed is 1. In a bracket, ahorizontally disposed arm, means to removably secure the inner end ofsaid arm to the stuclding of a building, a pair of pivotally mountedupwardly and outwardly extendingbars, means to support the pivoted endsof the bars from the studding engaging means, a wedge pivotally securedto the outer end of the horizontally disposed arm, and a link carried bysaid wedge and having a sliding connection with the pivotally mountedbars.

2. In a bracket, a horizontally disposed arm, means to removably securethe inner end of said arm to the studding of a building, a pair ofpivotally mounted upwardly and outwardly extending bars, means tovsupport the pivoted ends of the bars from the studding engaging means, awedge pivotally secured to the outer end of the horizontally disposedarm, and a link carried by and slidable with respect to the wedge andhaving a sliding pivotal engagement with the horizontally disposed armand a sliding connection with the pivotally mounted bars. 7

3. In a bracket, a pair of spaced horizontally disposed arms, means toremovably secure the inner ends of the arms to the studding ot abuilding, a pair of upwardly and outwardly extending bars, means topivotally support the lower ends of said bars from the arm securingmeans, a wedge pivotally secured'to the outer ends of the horizontallydisposed arms, and a link carried by said wedge and having a slidingpivotal engagement with the horizontally disposed arms and a slidingconnection with the pivotally mounted bars.

In a bracket, a pair otspaced hori-' zontally disposed arms, means toremovably secure the inner ends of the arms to the studding of abuilding, apair of upwardly and outwardly extending bars, means topivotally support the lower ends of said bars from the arm securingmeans, a wedge pivotally secured to the outer ends of the horizontallydisposed arms, and a substantially T-shaped link carried by andextending be yond the edges of the wedge and having openings therein toslidingly receive the bars, and also having a sliding pivotal connectionwith the horizontally disposed arms.

In testimony whereof I my signature.

JOHN ROMYAK.
